Proximal Hamstring Tendinopathy: The Injury That Sitting Athletes Get Wrong

Deep pain in the buttock that gets worse after sitting for a while, first thing in the morning, or when sprinting is one of the more frustrating presentations in sport. It is often dismissed as a hamstring strain, managed with rest and stretching, and then wonders why it takes months to resolve. In most cases like this the problem is proximal hamstring tendinopathy, and rest and stretching are not the answer.

What is proximal hamstring tendinopathy?

The proximal hamstring tendon attaches to the ischial tuberosity (the sit bone). Tendinopathy at this location develops when the tendon is subjected to compressive and tensile loads it is not conditioned to handle. It is particularly common in runners, cyclists, rowers, and anyone who spends long periods sitting, because sitting places the hamstring tendon in a position of combined stretch and compression against the ischium.

A 2021 expert consensus study in Physical Therapy in Sport found that experienced physiotherapists diagnose proximal hamstring tendinopathy primarily through clinical load-based provocation testing, not imaging. They also manage the injury through education, activity modification to reduce compressive positions, and progressive loading of the hamstring unit and kinetic chain (Nasser et al., 2020).

Why stretching makes it worse

The instinct when you feel tightness or aching in the hamstring area is to stretch it. For proximal hamstring tendinopathy, this is counterproductive. Hip flexion (the position your hamstring is in during a forward bend or a seated stretch) compresses the tendon against the ischium. In the early stages of tendinopathy, this compression provokes the tendon and maintains irritability.

The same applies to sitting with your hips flexed past 90 degrees, which is why people with this condition often find relief by raising their chair height or sitting on a wedge cushion.

What the evidence recommends

A 2023 systematic review in Sports (Basel) found that proximal hamstring tendinopathy responds best to a multimodal approach combining progressive tendon loading, lumbopelvic stability work, and in some cases extracorporeal shockwave therapy (Dizon et al., 2023). The review found that exercise at combined angles of hip flexion around 110 degrees and knee flexion between 45 and 90 degrees was most effective for tendon remodelling.

This is very specific, and it matters. Generic hamstring exercises done at short muscle length will not drive the structural adaptation the tendon needs.

Timeline and what to expect

Proximal hamstring tendinopathy is a slow condition. Four to six months of properly structured rehabilitation is typical. The frustrating part is that it often feels like it is getting better, then flares with a return to running or increased sitting load. This is why load management, beyond just exercise selection, is a critical variable.

At KINETIQ REHAB in Brunswick, proximal hamstring tendinopathy is managed with a staged loading program built around your specific aggravating activities and return-to-sport timeline. If you have had deep buttock pain that has not resolved with rest, come and get it properly assessed.
